Working under the mentorship of the discoverer of buprenorphine, John Lewis, PhD, the whole of the drug abuse field was focused on the coming approval of buprenorphine to treat heroin dependence. When approval came, we were overjoyed, and it brought an urgently needed medication that has helped thousands of individuals. 

Those were heady days, but the chemistry of opioids like heroin and morphine was at a bit of a crossroads; we had buprenorphine and methadone to treat dependence, and countless opioids approved to treat pain. So why would chemists be needed?  The focus shifted to the development of opioids with lower side effects (especially constipation), leading to the wonderful peripherally restricted antagonists that reverse the constipation but not the central analgesia.
